Microwave Popcorn

"The corn itself poses no cancer risk, but rather its packaging does.

The perfluorooctanoic acid (PFOA) used to waterproof the bag is potentially carcinogenic. 

What’s more, when heated in the microwave, these bags emit fumes high in diacetyl, a food additive used to add buttery flavor. 

Diacetyl is associated with lung disease and even the onset of Alzheimer’s disease. It’s best to prepare popcorn on the stovetop or with a popcorn maker."
